Radii in Runners…

I was asked this during NPE…

My guys want me to look into the ‘shear balancing’ runner technology while I am here… Is this stuff worth it, or do radiused runners work just as well?

My Response
Runner technologies which balance the shear imbalance within the runner system and are invaluable in helping to minimize cavity imbalances. Tricks such as radii runner intersections might improve the imbalance, but I have seen enough proof to know that shear balancing is the most effective method of correcting for runner imbalance.
